Sporophytes are typically taller than gametophytes because they are the dominant phase in the life cycle of plants, investing more energy in growth and reproduction. Sporophytes produce spores through meiosis, giving rise to new gametophytes, which are usually smaller and shorter-lived in comparison.
What else can I help you with?
Is the gametophyte the dominant generation?
in bryophytes the sporophytes is diploid(2n) while the gametophyte in bryophytes is haploid(n).In bryophytes the sporophytes are totally or partially dependent on gametophytes while gametophytes are the dominant generation in bryophytes.Male sporophytes produce male spores and that of female produce megaspores of female spores while male gametophytes produce male gametes while female gametophytes produce female gametes
When the spores of some plants grow the new plants are called what?
There new plants are called gametophtes
Is bryophytes a plant?
Bryophyta is a group of plants having thalloid independent gametophytic plants and their sporophytes remain dependent on gametophytes. Examples are Riccia, Marchantia, Anthceros and mosses.
Do spores turn into sporophytes?
A sporophyte is a plant element that carries the spores. The spores are the male reproduction seeds, that grow out to a whole new plant when fertilised.
Are microspores and megaspores produced by mitosis or meiosis?
Microspores and megaspores are produced by meiosis. In plants, microspores develop into male gametophytes (pollen), while megaspores develop into female gametophytes (embryo sacs). This process occurs in the reproductive structures of seed plants, where diploid sporophytes undergo meiosis to produce these haploid spores.

What are similaraties between angiosperms and gymnosperms?
Both bear seeds; both are vascular plants; Gametophytes in both groups are dependent on sporophytes

Is moss homosporous?
Yes, most mosses are homosporous, meaning they produce spores of the same size and type that can develop into either male or female gametophytes. These gametophytes then produce gametes that fertilize to form sporophytes.
What advance characteristic of sub-phylum Filicinophyta?
Ferns always have the following characteristics. (1)Plant bodies are better developed than bryophytes. Differentiation is obvious. Plant bodies possess the vegetative organs, as leaves and stems. But roots are still called rhizoids.(2)In their alternation of generations, the asexual generation predominate. The plant bodies in asexual generation are called sporophytes. The sizes of sporophytes range from 40 cm to 100 cm in height.(3)Sporophytes can produce asexual spores for the production of the gametophytes. Gametophytes can be free-living and possess chloroplasts for photosynthesis. Others may be parasitic in the sporophytes. For living forms, the gametophytes are called prothallus. A thallus is thin and have several layers of cells in thickness. So, they cannot resist direct sunlight.(4)Gametophytes can produce antheridia and archegonia. Antheridia produce antherozoids, the male gametes. Archegonia produce ova, the female gametes.(5)The primitive forms produce only one type of asexual spore. After germination, this unit type of asexual spore can produce both antheridia and archegonia. So, this type of plants are called homosporous. The advance form would produce two types of asexual spores, the megaspores and microspores. Megaspores can germinate to produce female gametophytes. Microspores can germinate to produce male gametophytes. Then, they are called heterospores. -ahang-
What is a primitive vascular plant?
Primitive vascular plants are also know as a pteridophytes but fern is their more common name. The ferns life cycle is split between sporophytes phases and free-living gametophytes unlike other vascular plants.
Are gametophytes of bryophytes larger than gametophytes of vascular plants?
this is bull i type the question and sometimes it shows mup but most of the time it doesnt :(
What do Hornworts get their name from?
Anthoceros is a genus of hornworts in the family Anthocerotaceae. The genus is global in its distribution. Its name means 'flower horn', and refers to the characteristic horn-shaped sporophytes that all hornworts produce. The dark color of the spores is the easiest way to distinguish Anthocerosfrom the related genus Phaeoceros, which produces spores that are yellow.The genus is distinguished by having spores that are dark brown to black, a relatively frilly thallus when compared to Phaeoceros, and larger and more internal cavities than Phaeoceros.
Are gametophyte better adapted to land environment?
Gametophytes are generally not as well adapted to land environments as sporophytes. While they play a crucial role in the life cycle of plants, particularly in non-vascular plants like mosses, they typically require moist conditions for reproduction and growth, as they rely on water for sperm mobility. In contrast, sporophytes, which are more dominant in vascular plants, have adaptations such as protective structures, roots, and the ability to produce seeds that allow them to thrive in a wider range of terrestrial environments. Thus, sporophytes are typically better suited for land life.
